PLOW.

Specification forming part of Letters Patent N 0. 44,215, datedSeptember 13, 1864.

To all whom it may concern:

Be it known that I, S. J. OLMSTED, of Bingin the county of Broome andState of New York, have invented a certain new and useful Improvement inPlows; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being bad to the accompanyingdrawings, and to the letters and marks thereon.

My improvement has for its object so constructing the mold-board of theplow as that it may be used to turn a wider or narrower furrow, and thisconstruction I produce by making the mold-board movable or adjustable.

The drawings forming part of this specificatiou represent a plow with myimprovement attached thereto and forming a part thereof, Figure 1 beinga side view on the mold-board side of the plow, and Fig. 2 being an endview,

showing the interior surface of the mold-board.

In each of these figures, where like parts are shown, like letters andmarks are used to indicate the parts.

The draft-beam a, share b, handles 0, and landside d of this plow do notvary from like parts of many plows, except so far as the curved line emay be regarded as a variation in the form of the rear part of theshare, if this curved line be made of theshare; but if made a part ofthe front section of the board, then the variation would moreparticularly apply to the board.

Upon a plate extending backward from the front section of the plow, asis shown by Fig. 2, f, the front part of the mold-board g is so attachedby a bolt and nut, or by some other suitable means or devices, as thatit may be turned up or down, the one position being shown in black linesand the other position in red lines in Fig. 1, and thus the action ofthe mold-board may be regulated so as to make the plow turn a wider ornarrower furrow.

Suitable means may be added to the moldboard, if necessary, to hold theboard in its adjusted position, such means being connected to the handleor beam of the plow. Instead of using the bolt and nut to hold the boardto the front section-piece, as is evident other means may be used, andthe bolt may be fitted in a slot instead of a hole, so that stillfurther adjustment of the board may be had.

This improvement may be made of any of the material and in any manner inwhich or of which it is common to make plows.

The practical advantages of the improvement are so readily seen and soreadily occur to the mind of every person interested insuch matters thatit is not necessary to dwell upon them.

What I claim as my invention, and desire to secure by Letters Patent,is-

Oonstructing plows with movable or adjustable mold-board, moving up ordown, substantially as herein set forth.

This specification signed this 20th day of May, 1864.
